关于$Λ_b^0\to pK^-γ$衰变的振幅分析

Towards an amplitude analysis of the decay $Λ_b^0\to pK^-γ$

Johannes Albrecht, Yasmine Amhis, Anja Beck, Carla Marin Benito

摘要:

本文首次提出了螺旋度理论在辐射衰变$Λ_b^0\to pK^-γ$中的应用。其目的是提供必要的形式主义,能够解决共振$pK^-$结构的光子极通过振幅分析。实验效果,如分辨率,也进行了讨论。

英文摘要:

The helicity formalism applied to the radiative decay $Λ_b^0\to pK^-γ$ is presented for the first time in this paper. The aim is to provide the necessary formalism to be able to resolve the resonant $pK^-$ structures at the photon pole by means of an amplitude analysis. Experimental effects, such as resolution, are also discussed.
